  • What’s UHVDC? It’s the future of power, that’s what

    Mar 12, 2019Unfortunately, most of the Chinese population is concentrated in urban areas on the coastlines. The power plants, on the other hand, are located much further inland. China solved this problem of distance by updating an old proposal for transmitting power over large distances. In 2010, it made history as the first country to take up UHVDC.
